A calcium carbonate media, the physical characteristics of calcium carbonate media: the media is a calcium carbonate mineral that has developed porosity, adsorption, widely used in desalination, adjust the PH value, large, medium and small water companies ideal product. Is to remove the effect of an inorganic ion exchangers in water but also with other Ca + Mg + Cs + K + Na + cation exchange etc. to measure heavy metals to reduce the total hardness of water, while it also has a large area, internal electrostatic strong, so that you can achieve the desired product water quality and drinking water quality standards for emissions. (Currently natural water calcium carbonate particles in two color gray and white particles, can be customized according to different specifications) of calcium carbonate filter characteristics: strong adsorption called but porous, large surface area of all dissolved solids role, while the chemical and physical reactions. When calcium's role as catalyst and water, there are two situations: physical adsorption # is the contact agent (media) atoms adsorbed on the surface suction over, become + and - the role of ion adsorption by grain size, ionization temperature three factors. # Is the chemical adsorption of the molecules of the solvent, it becomes decomposed + ions and - ions. Decomposition of atoms, ions are adsorbed on other substances. Calcium carbonate filter effect: This has a neutron absorption coupling and two electronic coupling, calcium carbonate is the two electronic coupling. Calcium carbonate as a medicine for skin diseases, especially pulling pus, very good. Calcium carbonate is porous, strong adsorption capacity, the main ingredient is calcium carbonate. In the electron microscope photography fine powder of calcium carbonate described above, it has been confirmed that the sponge-like porous, is the biggest reason. In other words, because the porous, the surface is very large, as part of feldspar weathering, such as kaolin-like, so always keep a strong adsorption, exchange interaction. Calcium absorption capacity is very strong this feature, has been confirmed by a number of experiments.
